In February, Fortis said it would buy U.S. power
transmission company ITC for $6.9 billion - its biggest deal
ever. It had said it would partly fund the deal by selling up to
19.9 percent of ITC to an investor, which it did not name.

"With the definitive agreement for the sale of 19.9 percent
of ITC to GIC, Fortis has completed a significant component of
the ITC acquisition financing," the three companies said in a
joint statement on Wednesday.
